of well established safety practices and a thorough knowledge of testing procedures. The testing procedures often

involve using equipment and materials that are potentially hazardous. Injury to personnel and damage to equipment

caused by fire, chemicals, dangerous pressures and vacuums, and misuse of equipment can be avoided by alert and

responsible laboratory technicians. Strict observance to established safety, care, and handling practices and procedures

will allow the laboratory personnel to perform their duties in a safe and hazard free environment.

1-1
TM 10-6640-233-10

1-7. General Precautions. The following are general safety precautions that need to be observed by all operators of

the AOAP Mobile Laboratory.

· Always be mindful to tests in progress. Never allow horseplay or loud talking that would divert the attention of

laboratory technicians. If it is necessary to leave the laboratory or to leave a test in progress, make certain no

safety hazard will result because of your absence.

• Do not attempt to perform tests simultaneously unless each test can be given the required attention.

· Whenever in doubt concerning any operation, consult your supervisor.

· Do not attempt unauthorized shortcuts to save time, as they generally are not in accordance with safe laboratory

procedures.

· Be prepared for any emergencies which may arise, and be familiar with the proper action to take in event of

emergencies.

· When ending daily operations, make a thorough and orderly check of laboratory, equipment, and facilities to

ensure that no hazards may develop during the time the laboratory is unattended.

1-8. Preventing Fires. The following fire prevention rules must be observed in all laboratory procedures:

· Do not smoke in the laboratory.

· Never leave open flames or heating elements unattended.

· Never pour hot liquids into drain. Set aside hot liquids to cool thoroughly in covered containers before

discarding.

· Make sure that chemicals which may react together to produce dangerous fumes, fires, or explosion are stored in

their proper places.

· Make sure that volatile liquids and flammable products are kept away from heat sources, open flames, direct

sunlight, and electrical switches.

· Make certain that there is no open flame or exposed heating element nearby when pouring highly volatile liquids.

· Clean up chemical and liquid spills immediately.

corrosive liquids such as strong acids and strong bases.

· When opening new bottles of acid, always wear goggles.

· When pouring a sample from a container, hold the container cap or stopper in the hand. Never place the cap or

stopper on a counter where it may come in contact with a contaminating agent.

· Always wipe up any acid that spills or splashes on benches, tables, or floors.

· If any chemical is spilled or splashed on the body, immediately wash the contaminated area thoroughly with

water.

· Keep all sample containers that are in use capped or stoppered at all times except when pouring out test

portions. Always replace the same cap or stopper in the container from which it was removed.

· Never handle mercury with bare hands; never heat mercury in an open container; and never shake more than 20

milliliters of mercury in a glass container.

• Never taste laboratory chemicals. Smell a chemical only when necessary and then only by wafting a small

amount of vapor with the hand toward the nose.

·Dispose of all unlabeled chemicals.

1-11. Controlling Pressure and Vacuum. The following safety precautions should be observed by all personnel

while operating the air/vacuum systems.

·Do not use faulty copper, plastic, or rubber tubing when performing operations requiring pressure or vacuum.

·Make sure that glass vacuum apparatus is properly shielded when it is in use.

·Always wear goggles when opening air valves that are close to the face.

Section III. TECHNICAL PRINCIPLES OF OPERATION

1-18. Functional Description of AOAP Mobile Laboratory Support Systems. The following paragraphs describe

the systems designed to support the AOAP Mobile laboratory. For details of major equipment, refer to the appropriate

equipment manual.

a. The semitrailer is divided into three individual compartments. Each compartment is separated from the next by

insulated metal bulkhead. The bulkheads separate the receiving compartment from the main laboratory, and the main

laboratory from the mechanical room. The forward bulkhead has a latched and lockable door capable of being latched

during transit. The aft bulkhead helps control the ambient temperature within the main laboratory by providing a separate

compartment for the receipt of samples and personnel entry and exit. Undercarriage compartments provided for stowage

of miscellaneous gear and overpack items (i.e., power reel, hosing, two 12-volt batteries, access ladders, etc.). These

compartments are separable to facilitate air transport (C 141 & C5A/B) of the AOAP Mobile laboratory. The AOAP

Mobile laboratory floor is of laminar design. It consists of formed aluminum sheets, polyurethane foam formed in place,

and a marine plywood subfloor with linoleum over it. Structural members that are on 16-inch centers and run the length

of the trailer provide load support adequate for equipment and personnel. The interior ceiling of the AOAP Mobile

laboratory contains the environmental air plenum and the fluorescent light fixtures. The light fixtures are contained within

hinged panels which are adjacent to the centrally located air duct. The hinged panels run the entire length of the

laboratory ceiling and provide access to both the light fixtures and the corresponding portion of the power distribution

system. The main and aft compartments have solid epoxy countertops, with steel cabinetry below. They are located on

the roadside and curbside wall areas which are not occupied by major floor-mounted equipment. The countertops serve

as mounting surfaces for smaller major items. Support apparatus and devices are located within the cabinets. The

cabinetry does not block or interface with the aisle or means of exit from any compartment.

b. Environmental Control System. The four Environmental Control Units (ECUs) are identical units, each with its

own controller. They operate on 208V, 60Hz, 3-phase power and are rated at 18,000 BTUs per hour when cooling and

12,000 BTUs per hour when heating. They are in fact heat pumps and provide both cooling and heating for the

laboratory. During the purge cycle, their blowers are utilized to over pressurize the laboratory and expel any explosive

gases. They are installed on the front wall, exterior of the semitrailer. The units do not transfer vibration to the

semitrailer nor are air leaks present at the intake or supply interface. The units are grounded and piping is provided to

remove the condensate from the air conditioning units to an outboard position on the roadside of the trailer. The

environmental controls are located in one panel/switchbox positioned in the main laboratory compartment, on the forward

roadside wall adjacent to the fume hood. The air conditioning portion of the control consists of two rotary switches and

one external thermostat. ECU controls No.1, 2 and 3 activate the three environmental control units supplying air to the

general environment duct. ECU control No.1, paired with an internal thermostat located within the computer cabinet,

activates and controls the environmental control unit supplying air to the equipment plenum. The heating controls consist

of two rotary switches, one for the equipment plenum and one for the general environment duct, neither of which

functions without the corresponding air circulating fans located within the environmental control units in operation.

Indicator lights are incorporated in the environmental control panel as an indication of operational feedback. Green is

used as an indication of normal computer operation.

1-15
TM 10-6640-233-10

c. The Electrical Distribution System (Figure 1-6) is 208-240 volts at 50-60 hertz. A power regulator (shielded and

grounded) is utilized to regulate the voltage requirements of both the primary and secondary electrical systems. The

primary electrical system provides power to the four air conditioning units, the 12 heating elements, the purging

fan/blowers, water pump, the air compressor and vacuum pump, and laboratory equipment requiring 220 volts. The

primary circuit panel is located on the roadside of the interior bulkhead dividing the utility and the main laboratory

compartments. The secondary electrical distribution system provides power for lighting and the laboratory equipment

requiring 110 volts ac. The secondary circuit panel is located in the aft compartment, on the curbside interior wall.

Instruments and gages deemed necessary for monitoring of service systems operating conditions are integral to the

secondary circuit panel (i.e., vacuum gage and pressure gage). A power entry receptacle is located on the forward

roadside exterior of the trailer. Located adjacent to the receptacle is a timer used to activate the environmental control

units when purging the laboratory of toxic fumes prior to entry. A cable reel assembly is provided on the undercarriage of

the trailer. The assembly contains the 100-foot cable required to interface with the 60 KW DED generator set. The

AOAP Mobile Laboratory has a 24-volt dc, emergency electrical system. Each of the van's three compartments contains

one 24-volt emergency lighting fixture capable of adequate illumination during emergencies. The batteries supplying the

24 volts required for the system, two 12-volt MS35000, are located in the cable reel box. A battery charger is also

provided to maintain battery charge while the laboratory is deployed. Laboratory equipment permanently affixed to

countertops or anchored in place is "hard wired" through switchboxes or motor starter-relay boxes mounted on the

curbside or roadside walls, as applicable. Wall outlets are provided at 3-foot intervals above the counter surfaces. All

outlets are "one-way" 110 volts ac. A microswitch is installed in each of the two trailer access door frames. Each

compartment is provided with an override switch to bypass the microswitch circuit for the door accessing it. Under

normal conditions, opening either van access door activates the blackout lamp(s) and deactivates the incandescent

and/or fluorescent lighting in the compartment serviced by that door. The power required by the computer and its

peripherals is filtered, shielded, and buffered. No additional power taps are available on the computer line other than

those required by the data system. The line runs from noise filter located in the primary switch panel directly to the

computer cabinet.

d. Lighting System. Lighting for the AOAP Mobile Laboratory is provided by 15 fluorescent ceiling light fixtures.

Thirteen are located in the laboratory compartment and two are in the mechanical room. Power for the laboratory

compartment lights is provided by circuit breaker main panel assembly.

(1) Blackout Lighting. The center lamp in each of the light fixtures is covered with a blue filter. When an access

door is opened, its door interlock switch is activated. This will turn off all white lights and leave energized all blue filtered

lights. When the access door is closed, the interlock switch is again activated, returning power to the white lights.

(2) Emergency Lighting. Emergency lighting is provided to the laboratory compartment by light fixtures and two

emergency light ballast boxes. When normal power is available, phase A power continually charges the battery device in

ballast box. The device in ballast box receives its charge from phase C power. When normal power is lost, power from

ballast box will be provided via the Forward Emergency Light Switch in the ON position. Power from ballast box will be

provided via the Rear Emergency Light Switch in the ON position.

1-17
TM 10-6640-233-10

e. Purge System. The purge system is used to exhaust potentially dangerous contaminated air inside the

laboratory to the outside. The system consists of the following components:

(1) Power control relay located in panelboard assembly number 1.

(2) Time delay relay located in explosion proof distribution box A3.

(3) Blower control relays located in explosion proof distribution box.

(4) Two purge intake doors and two purge exhaust doors located on the outside wall of the laboratory.

(5) Four purge door limit switches.

(6) Two intake dampers and two exhaust dampers located behind the external purge doors.

(7) Three ventilation dampers mounted in the ECU plenum located in the mechanical room.

(8) Seven purge damper motors.

(9) One purge alarm buzzer located at the power entrance panel.

A purge cycle can be initiated in two ways, one of which is by the application of external power after a power

shutdown, the other is by an alarm generated by the gas detector system. When external power is first applied, the

power required for a purge cycle is picked off ahead of the main circuit breaker. Main circuit breaker is held open by

power control relay. This prevents power from being applied to any equipment or lighting in the laboratory until the purge

cycle is completed. Relay routes the power that was picked off ahead of the main circuit breaker to start the 5-minute

time delay relay and to energize the four blower control relays which provide power to the ECU blowers. Power is also

routed to the purge door damper motors and to the ventilation damper motors so that the purge door dampers are

opened and the ventilation dampers are closed. The ECU blowers suck outside air into the ECU ducting where it is

dumped into the laboratory creating a pressure which forces any gases or contaminated air to the outside via the purge

exhaust doors. After 5 minutes have elapsed, time delay relay de-energizes. This causes power control relay to change

state which de-energizes relays. Power is removed from the ECU blowers, the dampers are driven to their normal

positions and the main circuit breaker may now be closed to supply normal power to the laboratory. If at the end of the

purge cycle the gas detector alarm system is in an alarm condition, the time delay relay is activated causing the cycle to

be repeated. This will continue until the alarm clears. When external power is applied and a purge cycle initiated, one of

the external purge doors is closed, the purge alarm buzzer will be activated by the purge door limit switch and will remain

activated until the door is opened.

f. Air System (Figure 1-7). The air system consists of the air compressor, air tank, pressure switch, moisture trap,

and associated piping and valves. The air compressor is located in the mechanical room and operates on 208V, 60Hz,

3-phase power. It can supply air at 120 psi to the system. In automatic operation, the compressor is controlled by a

pressure switch which shuts it off when the pressure has reached 120 psi and turns it back on when the pressure in the

system drops to 60 psi. The air tank relief valve is set to operate at 150 psi. There are air service valves located within

the main laboratory work area and are color coded orange.

1-19
TM 10-6640-233-10

g. Vacuum System. The vacuum system consists of the vacuum pump and associated piping and valves. The

vacuum pump is located in the mechanical room and operates on 11 0V, 60Hz, single-phase power. It has a free air

capacity of 58 liters per minute and supplies vacuum where required. Vacuum valves are color coded yellow and are

located in the main laboratory work area.

h. Water System. The water system consists of the water pump, pressure switch, water tank, filter, waste water

heater, water heater and associated piping and valves. The water pump operates on 11 0V, 60Hz, single-phase power.

It is controlled by the pressure switch. It turns on when a water outlet is opened and off when the outlets are all closed.

The water surge tank removes oscillations from the system while the water tank acts as the system supply source. The

water cooler operates on 11 OV, 60Hz, single-phase power. The water heater operates on 11 0V, 60Hz, single-phase

power. The system may be supplied with water from an outside pressurized source, from an outside unpressurized

source, by using the system pump, or by its own water tank. Water supply piping is color coded blue and valves are

color coded green. While water return piping and valves are color coded white, drain piping is colored black. Water

supply valves are located in the main laboratory work area. Cold water is marked CW and color-coded green and hot

water is marked HW and color-coded red.

i. Drain System. The drain system consists of valving and piping required to route condensate and waste water

from the sink to the deck drains located underneath laboratory exterior.

1-19. Functional Description of AOAP Mobile Laboratory Unique Equipment. The following paragraphs describe

some of the equipment mounted or stored within the laboratory. For equipment not described in these paragraphs, refer

to the appropriate equipment manual.

a. The fluid analysis spectrometer display (A/E35U-3A) (Figure 1-8) is a 1-meter emission spectrometer with an

LED liquid readout specifically designed for sample oil analysis. It has a console-type equipment cabinet permitting the

operator to carry out the routine procedures of analysis while seated at one location. Except for the main power circuit

breaker control, all operating controls are conveniently within the reach of the operator while in a seated position. Panels

have been designed to permit quick removal and provide access for performing required maintenance. The

spectrometer equipment includes personnel safety features such as safety interlocks, venting of noxious fumes, and

protection from ultraviolet rays. Equipment protective features include circuit breakers, fuse, interlocks, and venting.

Electromagnetic interference is controlled by RFI filters and proper grounding of all electrical components within the

instrument, while critical items have been individually shielded. The sample excitation chamber is interlocked to protect

the operator from high intensity ultraviolet light, shock from the carbon rod/disk are (22,000 volts peak), and exposure to

noxious or flammable fumes while sample analysis is in progress. During normal operation, the carbon arc will totally

"burn" the sample, leaving no residual flammable fumes or vapors. The chamber venting is adequate to purge the

chamber of all noxious or flammable/combustible fumes. The spectrometer is a preventive maintenance tool used to

determine the type and amount of wearmetals in lubrication oil samples of engines/transmissions and in fluids of

hydraulic equipment. The spectrometer is capable of detecting and measuring the concentration of the following

elements:

Iron (Fe) Nickel (Ni) Cadmium (Cd)

Silver (Ag) Lead (Pb) Molybdenum (Mo)

Aluminum (Al) Silicon (Si) Zinc (Zn)

Chromium (Cr) Tin (Sn) Sodium (Na)

Copper (Cu) Titanium (Ti) Manganese (Mn)

Boron (B) Magnesium (Mg) Vanadium (V)

Barium (Ba) Beryllium (Be)

The operation of the spectrometer is based on the atomic emission technique. This technique depends on the fact that

atoms of elements can be energized (excited) to emit radiant energy when exposed to a suitable excitation source.

When this radiant energy is dispersed by either a prism or a diffraction grating, it emerges as a light spectrum having a

pattern determined by the structure of the atoms that have been excited. Since atoms of different elements contain

different electron configurations, each element has a distinct and characteristic spectrum, with spectral lines occurring at

different wave- lengths. Each element can be identified by its characteristic lines. In quantitative analysis, line

brightness represents element concentration in the sample. Line brightness is converted from radiant energy into

electrical energy by a suitable photomultiplier tube. The electrical signal at the output of the photomultiplier tube is

processed and displayed on a readout device.

The spectrometer can be divided into seven main groups. The groups have been given titles according to their

functions, and with the exception of a few items, assemblies and subassemblies are physically located in the cabinet or

chassis of their respective groups. The groups are as follows:

a. Sample excitation group e. Integration group

b. Optical processing group f. Power distribution group

c. Control group g. Optional group (automatic printer)

d. Electronic processing group

1-21
TM 10-6640-233-10

Figure 1-8. Fluid Analysis Spectrometer

The sample to be analyzed is electrically excited in the analytical gap. Light from the resulting arc passes through the

entrance lens where the light is formed into a beam. The beam passes through a deflection plate which swivels back and

forth during the integration process. This motion deflects the beam away from its direct (or forward) path providing

background light subtraction. The beam then strikes the grating, which acts as a prism to disperse the light into spectral

lines. Each spectral line of interest passes through its exit slit (located on the focal curve) to the photomultiplier (PM)

tube of the channel assigned to the spectral line. The PM tube converts the light into electrical current that builds up a

charge on the integrating capacitor of the subject channel. The analog voltage on the capacitor is processed by the data

conversion circuitry and fed to the readout electronics circuits.

b. The AOAP Standard Data System (SDS) (Figure 1-9). The information generated from the spectrometer can be

displayed on the numerical LED indicators or printed out by the autoprinter interface which is used by the AOAP

Standard Data System (SDS). The AOAP SDS is comprised of the following modular components:

f. Duplex Ferrograph System (Figure 1-14). The Duplex Ferrograph System consists of the Dual Ferrograph

Analyzer, Direct Reading Ferrograph, and a ferroscope with camera. The duplex ferrograph is located in the curbside

storage box.

(1) The dual ferrograph is designed with two stations for making ferrograms, side by side. Operated

simultaneously or separately, each ferrograph station magnetically precipitates ferrous wear particles from the samples

and deposits them selectively on a thin glass slide called an ogram. After the oil is washed away by a solvent, the

remaining particles are left affixed to the glass slide. The ferrograms are then analyzed with the ferroscope.

(2) The ferroscope is a special bichromatic microscope system developed for fast and efficient ferrogram

analysis. With both reflected and transmitted light and magnifications of 100X, 500X, and 800X, the ferroscope readily

identifies wear particle size, shape, texture, and color. The system includes a 35mm camera to record particulate data.

two remote detector assemblies. The main control unit is wall-mounted on the roadside and connects electrically to the

two detector assemblies. The system operates on 110V, 60Hz, single-phase power. The main control unit supplies 5.5

Vdc to the detectors. The alarm is calibrated for propane and has a setting of 20 to 40 percent of the lower explosive limit

(ell) of gasoline. An indicating meter in the control unit shows the concentration being monitored and adjustable duallevel alarm circuits are triggered whenever a concentration exceeds the ell. The alarm alerts personnel of combustible

almost all laboratory reagents, except HF. Very strong oxidizing acids, such as nitric acid and organic solvents at high

concentrations, may cause some warping of the fluorocarbon, which could adversely affect the performance of the

instrument. The fumes from organic solvents (such as toluene) may attack the magnifying indicator. Only glass and

1-20. Laboratory Operating Procedures. The following scenario pertains to the AOAP Mobile Laboratory processing

selected aeronautical and nonaeronautical oil samples in a tactical environment. Further, it is not to be conceived as the

"ONLY" way of performing specified AOAP analysis.

a. The process begins with the soldier in the field who takes an oil sample and fills in applicable data elements on

a DD Form 2026, Oil Analysis Request. The completion of this form, which accompanies the sample to the laboratory, is

critical to the success of the analysis, since all data relating to the component from which the oil was taken is entered off

this form. Component serial number, hours since last oil change, and hours since last overhaul are examples of data

required by the evaluator for accurate assessment of component wear or changes to the lubricating oil's physical

properties.

b. On receipt of the oil sample at the AOAP Mobile Laboratory, the components sample's header information is

entered in the AOAP Mobile Laboratory's Standard Data System (SDS) computer. The SDS assigns an index number to

each serial numbered component. The index number is where the current and/or historical analysis information is stored

in the computer, which is retreived by entering components serial numbers.

c. The oil sample at this time can have spectrometric or physical property analysis performed, since the

aeronautical oil samples require only spectrometric analysis to be performed, except for selected AH- 1's components

requiring ferro graphic analysis. Thus, for discussion purposes ONLY, oil analysis process will begin with spectrometric

analysis test, which is performed on all components enrolled in AOAP.

d. The oil sample is analyzed for up to 15 wear metals on the spectrometer. The spectrometer is interfaced with a

Wang MICROVP-2 computer system. This system has been loaded with AOAP wear metal guidelines for components

enrolled in AOAP. If element(s) exceed(s) the specified spectrometric guidelines for that component, then the evaluator

reviews analysis data and makes a recommendation to the owning unit. These recommendations can range from an oil

and filter change to the removal of the component from service. To ensure the proper operation of the spectrometer, the

operator performs daily standardization checks on the instrument before each day's start up. However, if the

spectrometer does not pass these prescribed daily standardization checks, then a complete standardization is performed.

Additionally, periodic standardization checks are made throughout the day. At a minimum, these checks are made when

switching from analysis of aeronautical to nonaeronautical samples (and vice versa), or whenever the spectrometer has

not been operated for 30 minutes or more.

e. Physical property testing is performed on nonaeronautical engine and transmission oil samples to determine the

on-condition of the oil in these components.

f. The Crackle Test is performed utilizing a hot plate set at 300 to 350 degrees Centigrade (150-175 degrees

Fahrenheit) surface temperature to ascertain presence of water contamination. This test is accomplished by placing one

drop of oil on the surface of the hot plate. A positive test is indicated by an audible crackling and spattering of the oil.

g. The determination of the viscosity of used oils is performed using a Direct Readout Viscometer. The viscosity

reading is obtained by immersing the viscometer's vibrating sphere into the nonaeronautical oil sample. If the viscosity

reading of the used oil sample obtained is below the prescribed lower criteria guidelines, then additional testing is

conducted to determine if fuel dilution, contamination, or lubricant degradation has occurred. Additionally, if the viscosity

readings obtained are above the upper criteria, then the evaluator may recommend an oil and oil filter change.

1-33
TM 10-6640-233-10

h. The Blotter Test is used to determine the insoluble contaminants, dispersant ability, and alkalinity of used oil from

diesel engine samples. This test is performed by placing one drop of used oil in the center of an oil print filter circle. The

oil spot is allowed to develop for 15 minutes, and the resulting spot is evaluated for total contaminants, cooling

contaminants, and dispersant effectiveness. An alkalinity indicator is added to the spot and, after one or two minutes, the

alkaline reserve is determined from the color ring that develops.

i. The Flash Point Tester is used in determining the percentage of fuel dilution in used oil samples from diesel

engines.

j. The Microscopic Analysis Test is used to determine wear and contamination of suspect spectrometric oil samples

from aircraft components as relates to the components condition. This is accomplished by placing a few milliliters of the

suspect oil sample in a test tube and mixing with solvent. This mixture is then filtered through a .01 45u (Micron)

membrane filter. The remaining insoluble debris and filter membrane are carefully rinsed with solvent to remove oil and

then allowed to air dry. The dry membrane is transferred to a petri slide and the debris examined under a low-power

microscope. The debris are identified as to type of wear metal with respect to wear and contamination.

k. Ferrographic analysis is currently performed on selected aeronautical components (i.e., AH-l swashplates and

Scissors & Sleeves Assembly) as a supplement to spectrometric analysis.

The Metric System and Equivalents

Linear Measure Liquid Measure

1 centiliter = 10 milliters = .34 fl. ounce

1 centimeter = 10 millimeters = .39 inch 1 deciliter = 10 centiliters = 3.38 fl. ounces

1 decimeter = 10 centimeters = 3.94 inches 1 liter = 10 deciliters = 33.81 fl. ounces

1 meter = 10 decimeters = 39.37 inches 1 dekaliter = 10 liters = 2.64 gallons

1 dekameter = 10 meters = 32.8 feet 1 hectoliter = 10 dekaliters = 26.42 gallons

1 hectometer = 10 dekameters = 328.08 feet 1 kiloliter = 10 hectoliters = 264.18 gallons

1 kilometer = 10 hectometers = 3,280.8 feet

Square Measure

Weights

1 sq. centimeter = 100 sq. millimeters = .155 sq. inch

1 centigram = 10 milligrams = .15 grain 1 sq. decimeter = 100 sq. centimeters = 15.5 sq. inches

1 decigram = 10 centigrams = 1.54 grains 1 sq. meter (centare) = 100 sq. decimeters = 10.76 sq. feet

1 gram = 10 decigram = .035 ounce 1 sq. dekameter (are) = 100 sq. meters = 1,076.4 sq. feet

1 decagram = 10 grams = .35 ounce 1 sq. hectometer (hectare) = 100 sq. dekameters = 2.47

acres

1 hectogram = 10 decagrams = 3.52 ounces 1 sq. kilometer = 100 sq. hectometers = .386 sq. mile

1 kilogram = 10 hectograms = 2.2 pounds

1 quintal = 100 kilograms = 220.46 pounds Cubic Measure

1 metric ton = 10 quintals = 1.1 short tons

1 cu. centimeter = 1000 cu. millimeters = .06 cu. inch

1 cu. decimeter = 1000 cu. centimeters = 61.02 cu.
